We don't have an IT person at my office and as the defacto IT guy it's increasingly becoming my job to fix everyone's problems.
Last Friday a few girls computer's weren't able to connect to the internet or the network. I left early but the moans came first thing this morning. I investigated a bit and it turns out that the DHCP server wasn't assigning IP's correctly.
I checked the hardware as much as i could. We have a big router that dishes out the network to each computer individually with the exception of one 4 port switch. Here the line runs to one unused computer (i'm not sure if that was out or not) one used computer, and a WAP.
The computer connected directly to the switch and the computer that utilizes the WAP weren't getting their IP's. I fixed the problem by manually assigning them but i see this more as a temporary fix. As far as i know, that switch gets it's data right from the router, just like all the other computers in the office which are working fine. So why would those coming from the switch suddenly not be receiving IP's?
